Abstract (en)

[origin: EP2281653A1] A method of friction welding comprising providing a first workpiece (24) having a first weld surface (38) and a second workpiece (26) having a second weld surface (40). In a first region (42) adjacent the first weld surface (38) the first workpiece (24) is arranged at an angle (±) of substantially 90° to the first weld surface (38) and in a second region (44) adjacent to the first region (42) the first workpiece (24) tapers away from the first weld surface (38). The first workpiece (24) is arranged such that in the second region (44) the first workpiece (24) is arranged at an angle (²) greater than 90° and less than 180° to the first weld surface (38). The first and second workpieces (24, 26) are arranged such that first weld surface (38) of the first workpiece (24) abuts the second weld surface (40) of the second workpiece (26). The first and second workpieces (24, 26) are moved relative to each other such that the temperature increases at the weld surfaces (38, 40) to create a weld interface (46) and then the movement is stopped to cool to weld the first and second workpieces (24, 26) together.
